In relation to the original post... I want to clear atleast 35's on my truck, and possibly 37's if I could just to be unique. What would really be needed for that? I know Greg is getting ready to release a lift kit design that he got from another company. So my thoughts were what would be a better route, suspension lift plus body lift to clear the tires? Or go with a Titanswap? whats the average cost on a titan swap these days for the parts?
37s won't happen. Well, it would take a whole hell of a lot of suspension and body lift (more than I think is currently available) plus fiberglass fenders or chopping the fenders not shaving but chopping. Most guys have a difficult time with 35s, still a hell of a lot of lift and shaving. 33's is optimal for these trucks, hence the amount of us that run them. Plus, the R180 front diff is your truck's weakest link. Wheel 33s wrong and it snaps, put 35s on and it grenades. $hit, look at it wrong with 35s and it explodes. Some guys have been real lucky/careful and wheeled their 35s on a R180 diff and haven't blown it yet, but it's all driver and laying off the gas when your off the hardball road.
To replace that front diff, you can swap it with a Titan M205 front diff. Now you can keep your same track and install the titan diff with V8 pathfinder axle shafts or do the Titan front suspension swap as well. Anyway you look at it, you will be paying a metric f-ton for parts and if you can't do it yourself, factor in another f-ton in labor.
You might as well try and do a solid axle swap if you really want 37s. Key word is "TRY" the SAS. There is a reason why there aren't any on this forum. There is one guy in the process, and his budget is like $12k or so. Good luck man, hope this helps.
